The AguaCheck Wireless Stock Tank Sensor is designed to allow one to monitor a remote water tank, which includes status reports daily and low-water-level or rapid-water-loss alerts instantly, all via text messages. Set-up involves mounting the solar-powered device at the top of the tank and lowering the weighted tubing into the water. Among the cited benefits: knowing when to turn a pump on and off without wasting time or overflowing a tank, lowering pump electricity cost, detecting a broken float valve or other leak before the tank is drained, and enabling water usage planning and rationing.
